' outside of the space bordered by the needles. The invention consists in arranging the plate carrying the mechanism within that space. This condition, however, requires special holding means for the stationary needles. The invention consists further in providing shoes which are secured to the letter file cover and are adapted to removably receive the file needle mechanism.

Referring now to the drawings in which the same numerals refer to like parts throughout and in which Figure 1 is a top view with the mechanism removed,

Fig. 2 is a top View showing the letter file mechanism secured in place, Fig. 3 is a front view of the letter file mechanism, a

Fig. 6 is a side view of the operating handle, and

Fig. 7 is a top View of thehandle.

The movable needles 8 and 9 are integrally connected together by an intermediate stay member 5 which has a horizontal crooked portion 5 upon which a spring 35 exerts an upward pressure as shown in Figs. 2 and 4. Pressure lever 19, by means of roll 20, may depress the crooked portion 5 against the pressure of the spring 35. The stationary needles 6 and 7 are also integrally connected and have horizontally bent portions 6 and 7 adjacent each of said stationary needles. These needles 6 and 7 are connected by an in termediate stay member 4:. The stays are located parallel to each other and as close together as the crooked portion 5 permits. The base plate 15 is provided with rim lugs 29, 30, and 31 which embrace their respective I 3 stay members i and 5. To stiti'enor strength en the stationary needles, the horizontal portions 6 and 7 are provided at their feet, withwhich portions these needles may. abut against the back of the mechanism. Furthermore, the connecting stay 4 of these needles is provided in its middle portion with a vertical crooked portion 16 secured against a cheek 17 formed by a rectangularly bent-off part of is the just-mentioned crooked portion and the cheek onthe base plate, form holding or sup-' porting means which maintain the needles 1n their proper posltlon. The rim lug 82 'holdsand secures the crooked portion 16 and is integral with the cheek portion 17 The cheek 17 comprises at the same time a support and pivot point for the pressure lever 19. This lever is guided by a shield 18 which forms a part of the lever 19. This cheek and shield have circular offset portions at approximately the center of each and directed towards and abutting against each other. A rivet 24 connects these two members together and is adapted topermittheshield 18 to rotate thereon. Thelever handle consists of a wire loo-p connected with the shield 18 by bent over cars 19 and 19'. One free end 22 of the wire passes through the shield and carries a roll 20 which has been referred to above and the other free end has the bent end 21 extended into the shield 18. Said por tion 22 is positively guided in. a slot 23 provided in the check 17.

Thev mechanism may be fastened to the cover of the letter file by means of shoes 2 and 3 of U-shaped cross-section and provided with tongues 36 cut out of their end portions.

The shoe may be made as wide as possible in order toaccommodate various widths 0-1 letter file InechanismCas shown in dotted lines in Fig. 2 or the distance between the shoes may be varied. The shoes have incisions 25,

26, 27 and 28 provided in the oppositely lo- 100 I cated flanges, the connecting stays i and 5 of the stationary needles 6 and 7 and the movable needles 8 and 9 fitting into said incisions. Overlap-ping lugs 10 and 11 are stamped from shoe 2 and overlap-ping lugs 12 and13 105 are stamped from shoe 3, said lu'gs being integral with said shoes. After the letter file mechanism has been shoved below the overlapping lugs 10, 11, 12 and 13 of said shoes, a

bail 14 forming an elastic bow which rotates the base plate 15. Both of these parts, that H in holes in o-pposed flanges of said shoes, is forced against the cheek l7 and locks the mechanism to the shoes.

I claim as my invention:

1. A letter-file mechanism, comprising, in combination, stationary needles each having at its foot a bent portion adapted to bear upon the letter-file cover; a stay connecting said bent portions with each other; a base plate lying between said needles; means connecting said stay with said plate; movable needles connected together by a stay having a crooked portion; means for pivoting said latter stay on the base; and means for operating said movable needles including a pivotal'lever having a roll thereon adapted to engagethe crooked portion of said movable needles.

2. A letter-file, comprising a base plate having an extension; stationary and movable needles; stays connecting said needles to the base plate and secured therein; shoes having lugs thereon to removably receive said stays; means for operating said movable needles including a lever pivoted to said extension; and means for locking said base plate to said shoes.

3. A letter-file mechanism, comprising, in combination, stationary needles; a stay connecting said needles with each other and comprising an upwardly directed crooked portion; a base plate lying between said needles; a projection extending upwards from said plate at the side of said crooked portion; a lug formed integral with said projection and being bent over the said crooked portion; movable needles,and means for operating said movable needles substan tially as described.

4. A. letter-file mechanism, comprising, in combination, stationary needles, a stay connecting said needles with each other and comprising an upwardly directed crooked portion, a base plate lying between said needles; a projection extending upwards from said plate at the side of said crooked portion; movable needles, and an operating lever for said needles comprising a shield, said shield being arranged opposite to said "projection; and said lever being attached to said shield, substantially as described.

5. A letter-file mechanism, comprising, in combination, stationary needles; a stay connecting them with each other a base plate between said needles; a projection extending upwardly from said plate and having a slot therein; movable needles connected together by a connecting stay comprising a crooked portion; an operating lever for said needles comprising ashield, said shield being arranged opposite to said rojection; and a roll mounted upon said lever between the projection and the shield, and being adapt ed to press upon the crooked portion of the connecting stay of the movable needles of the mechanism, said roll and the lever being guided and limited in their movement by said slot.

6. A letter-file, comprising a file cover; a base plate; stationary and movable needles; astay member connecting each needle to said base plate; means secured to said base plate for operating the movable needle; and means on said cover for removably securing said base plate by means of said stays.

A letter-file comprising a base plate; stationary and movable needles; a stay member connecting each needle to said base plate; means secured to said base plate for operating the movable needles; and means for removably securing said base plate by means of said stay members to any support.

8. A letter file comprising a base plate provided with a check portion; stationary and movable needles comprising stay members; means for securing the same to said base plate by means of said stay members; and an operating lever pivoted to said cheek portion adapted to operate the movable nee dles said stationary needles being provided at their feet with bent horizontal portions between their stay member and the needles, and a vertical crooked portion in said stay member and associated witii said cheek.

9. A letter file comprising stationary needles connected by a horizontal stay member, the base of each of said stationary needles being provided with a bent horizontal connection stay connecting the needles with the horizontal stay member; movable needles; a base plate for said needles and located between the needles; and means for operating said movable needles.

In testimony whereof I have aliixed my signature.
